Controls and Functions

Front Panel

(1) Microphone Connector (SP/MIC)
Connect the supplied speaker-microphone to this connector. Speaker audio is
provided by the speaker-microphone.
If you wish to use your own microphone rather than the supplied speaker-
microphone, you may rewire your microphone cable.
However, you will need to use your own external speaker connecting to the SP
OUT of the rear panel of the ARD9000MK2 as it does not have a built-in internal
speaker.
Below is a pin assignment of the speaker-microphone connector of the
ARD9000MK2.
